Was Kristen seduced by her married director? Her friend says so!

“Rupert’s manipulative,” an insider tells Us Weekly. “She didn’t go after this guy — he sought her out and she stupidly went for it.”

Though Kristen has since apologized — profusely — to her boyfriend of three years, Robert Pattinson, sadly, the two have not been able to reconcile. “He just doesn’t get why she did it,” admits the insider, but adds that “he loves her and thinks about her constantly.”
